- Preparation and Feeding Information
- PWT 1082 is a single component emulsion polymer that must be pre-diluted in water before use.
- In most cases, this product should not be applied neat.
- One method for dilution is adding the neat polymer into the vortex of a mixed tank at a concentration between 0.25 - 1.0% polymer (0.5% is optimum) by weight.
- The polymer can also be injected through a number of commercially available systems that provide in-line mechanical mixing.
- Polymer solutions should be aged for 30-60 minutes prior to use for best results.
- Solution shelf life is 8-16 hours.
- Uses
- PWT 1082 is a high charge, high molecular weight anionic polyacrylamide in emulsion form.
- It is used as a flocculant in a wide variety of municipal and industrial wastewater treatment applications.
- It has been successfully applied in liquid/solids separation systems, including clarification and dewatering.

Storage & Handling
- Storage, Stability and Handling Information
- Suggested in-plant storage life is one year in unopened drums.
- For best results, store at 50-80°F.
- Bulk tanks should be mixed by periodically recirculating the contents bottom to top.
- Bulk tanks can also be fitted with an agitator type mixer that reaches the bottom 2 feet of the tank.
- Do not allow emulsion polymers to freeze.
- Should freezing occur, allow the product to thaw thoroughly in a heated area and mix well before attempting to use it.
- For spills of PWT 1082, sprinkle salt, vermiculite or equivalent absorbent over the spill area and sweep the material into approved chemical disposal containers.
- Do not spray water onto a spill because the resulting gel is very difficult to clean up.
- Materials of Construction
- Cross-linked polyethylene, fiberglass, stainless steel or lined steel are the preferred materials of construction for bulk tanks.
- Avoid natural rubber and Buna-N gaskets as these materials swell when placed in contact with neat polymer.
- Unlined mild steel, black iron, galvanized steel, copper or brass are not recommended in any part of the feed system.
- Stainless steel, Viton or Teflon are the best choices for pump heads. For feed lines, polyethylene, PVC or reinforced Tygon tubing is recommended.
